This is for the most part 100% painfully true, source: I did 5 years of art college, majored in media arts and digital tech with a minor in animation.
Every single teacher in drawing hated or otherwise discouraged realism, anime, but were fine with cartoons or western styles no matter how derivative or bad. Some students didn't even fucking hand in drawings in some more 'open' assignments, but instead produces installations, sculptures, one girl didn't talk for 48 hours and called it a piece.
With that said, 'drawing' was mandatory for all 1st years, so I can understand why they were so open/vague since everyone no matter what skill or specialty had to fucking do it: one girl was going into fibre and she made the most amazing, absolutely fantastic, fake-mounted-taxidermy animal heads entirely out of coloured felt.
The only instructor I had whom actually respected and encouraged the development and practice of drawing was my animator instructor. He was an extremely unusual and charismatic old man: he had done animated films for the independent Canadian film board, had been in the trade for almost 40 years, and had an encyclopedic knowledge of western animation and anime (he had an entire portal drive devoted to inspiration/source material that he'd let people download for free at any time: it had books, all the ghibli films, old disney films, etc..)
He wouldn't let us even touch a computer till we passed this pencil and paper animation test: we had to do a bouncing ball, bag of flour, one transformation, and a walk cycle, and the whole thing was then put together on a machine called a 'lunch box'. Only after that would he accepted things done in photoshop, toon boom, aftereffects, etc.. He taught aftereffects and photoshop during the evenings and had pdfs of every single text book he recommended in case you couldn't afford it.
